Example 1
As shown in fig. 1 to 4, a valve linkage device provided in an embodiment of the present invention includes: electric actuator 10, linkage rope 20 and valve linkage, wherein:
the valve linkage includes a first linkage 30 and a second linkage 40.
The electric actuator 10 is used for driving the first spindle rotation rod 31 in the first linkage mechanism 30 to rotate.
The first linkage mechanism 30 is connected with the second linkage mechanism 40 through a linkage rope 20, and the first linkage mechanism 30 drives the second main shaft rotary rod 41 in the second linkage mechanism 40 to rotate through the linkage rope 20.
The valve linkage device provided by the embodiment can be applied to valves, in particular to large smoke-proof and fire-proof valves. Specifically, the first spindle rotating rod in the first linkage mechanism and the second spindle rotating rod in the second linkage mechanism are respectively connected with different valve groups in the large valve, and one valve group can comprise one small valve or a plurality of small valves in transmission connection with each other. In the normal state, the valve is in an open state. When the valve needs to be closed, the electric actuating mechanism is started, and the electric actuating mechanism is electrified to drive the first main shaft rotary rod in the first linkage mechanism to rotate so as to drive the valve plate in the valve group connected with the first main shaft rotary rod to rotate. When the first main shaft rotating rod rotates, the second main shaft rotating rod is driven to rotate through the linkage rope, so that valve plates in valve groups adjacent to the second main shaft rotating rod are driven to rotate, and each valve plate in the valve is rotated, so that multiple groups of valves in the whole large valve are closed.
As shown in fig. 2 and 3, in a specific implementation of the present embodiment, the first linkage mechanism includes: the first main shaft rotating rod 31, the first locking piece 32 and the first elastic driving piece 33, wherein the first locking piece 32 is detachably connected with the first main shaft rotating rod 31, the first elastic driving piece 33 is used for driving the first main shaft rotating rod 31 to rotate, and the first elastic driving piece 33 is in a force storage state when the first main shaft rotating rod 31 is locked with the first locking piece 32; the electric actuator 10 is used for driving the first locking member 32 to move so that the first locking member 32 is separated from the first spindle rotation rod 31. That is, the electric actuator 10 is unlocked from the first spindle rotation lever 31 by driving the first locking member 32 after being energized, thereby achieving the purpose of driving the first spindle rotation lever 31 to rotate.
As shown in fig. 4, the second linkage includes: the second spindle rotating rod 41, the second locking piece 42 and the second elastic driving piece 43, wherein the second elastic driving piece 43 is connected with the second spindle rotating rod 41 and used for driving the second spindle rotating rod 41 to rotate, the second spindle rotating rod 41 is detachably connected with the second locking piece 42, and the second elastic driving piece 43 is in a force storage state when the second spindle rotating rod 41 is locked with the second locking piece 42.
As shown in fig. 1, the first spindle rotating rod in the first linkage mechanism 30 is connected with the second locking piece in the adjacent second linkage mechanism 40 through the linkage rope 20, and the first spindle rotating rod can drive the second locking piece to move when rotating, so that the second locking piece is separated from the second spindle rotating rod, and the second spindle rotating rod is driven by the second elastic driving piece to rotate, so that the valve plate corresponding to the second spindle rotating rod is driven to rotate. That is, the first main shaft rotating rod drives the second locking piece to unlock with the second main shaft rotating rod after rotating, thereby realizing the purpose of driving the second main shaft rotating rod to rotate.
So set up, when closing the valve, start electric actuator, electric actuator drives first locking piece motion to make first locking piece and first main shaft dwang separation, first main shaft dwang rotates under the effect of first elastic drive spare after separating with first locking piece, thereby drive the valve block in the valve group rather than linking to each other on the one hand and rotate, on the other hand drive through the linkage rope with its adjacent second locking piece motion in the second linkage mechanism, thereby make second locking piece and second main shaft dwang separation, the second main shaft dwang rotates under the effect of second elastic drive spare after separating with the second locking piece, thereby drive rather than linking to each other's valve group rotation.
Further, the valve linkage device controls the valve to close when the ambient temperature of the valve is too high. Alternatively, as shown in fig. 2 and 3, in the valve linkage device, the first linkage mechanism further includes a mounting plate 50 and a fuse 60 mounted on the mounting plate 50, the mounting plate 50 is hinged with a fusing linkage rod 70, one end of the fusing linkage rod 70 is connected with the first locking member 32 through an elastic rotating member 71, and the other end is abutted to the fuse 60.
In the normal working process of the valve, the two ends of the fusing linkage rod are respectively in a balanced state due to the action of the elastic rotating piece and the fuse, when the temperature is too high, the fuse breaks, so that the fusing linkage rod is separated from the balanced state and rotates, and the fusing linkage rod drives the first locking piece to move in the rotating process, so that the first locking piece is separated from the first main shaft rotating rod. The first spindle rotating rod drives the valve plate in the valve group connected with the first spindle rotating rod to rotate and drives the second spindle rotating rod to rotate, so that the valve plate in the valve group connected with the second spindle rotating rod rotates (the specific transmission process is the same as the transmission process when the electric actuating mechanism closes the valve, and the detailed description is omitted here), and the valve is closed.
Further, the first locking piece and the first main shaft rotating rod can be detachably connected through a clamping groove. For example, the first locking member may be a locking lever, for convenience of description, referred to as a first locking lever, where a middle area of the first locking lever is hinged to the mounting plate, one end of the first locking lever is connected to the electric actuator, and a side surface of the other end of the first locking lever is provided with a clamping groove, and a part area of the first spindle rotating rod extends into the clamping groove to be in clamping connection with the first locking pin lever. The electric actuating mechanism drives one end of the first locking lever to rotate, so that the other end of the first locking lever moves in a direction away from the first main shaft rotating rod to be separated from the first main shaft rotating rod.
Further, the second locking piece and the second main shaft rotating rod can be detachably connected through a clamping groove. For example, the second locking member may be of the same construction as the first locking member, i.e. the second locking member may also be a locking lever, called second locking lever, the middle region of which is hingedly secured, in particular in the housing of the valve to which it is applied. One end of the second locking lever is connected with the linkage rope, a clamping groove is formed in the side face of the other end of the second locking lever, and a part of the second main shaft rotating rod can extend into the clamping groove to be clamped with the second locking lever. The second locking lever is connected with the first main shaft rotating rod through the linkage rope, the linkage rope is pulled in the rotating process of the first main shaft rotating rod, and the linkage rope pulls the second locking lever, so that the second locking lever rotates around the hinge position of the second locking lever, and the other end of the second locking lever moves in a direction far away from the second main shaft rotating rod and is finally separated from the second main shaft rotating rod.
As shown in fig. 3, in a specific implementation manner of this embodiment, the electric actuator includes an electromagnetic driver 13, a spring 14 and a connecting piece 11, where the electromagnetic driver 13 is electrically pulled to pull the connecting piece 11 to drive one end of the first locking piece 32 to rotate, and release the first spindle rotating rod 31 to rotate the first spindle rotating rod 31. The connecting sheet can be made of non-magnetic metal materials.
Specifically, a spring is arranged between the electromagnetic driver and the connecting sheet, and after the electromagnetic driver attracts the connecting sheet, the connecting sheet compresses the spring, and the spring is in a force storage state. After the electromagnetic driver is powered off, the spring pushes the connecting sheet to move reversely, so that the connecting sheet is reset.
In any of the above embodiments, with continued reference to fig. 3, optionally, a manual pull cord 81 is attached to the first locking member 32. The manual pull cord 81 is used when installing and adjusting the valve linkage, or manually adjusts the open and close state of the valve in an emergency in which the system is powered off. A manual pull cord 81 is tied to one end of the first locking member 32.
In one embodiment of the present embodiment, as shown in fig. 4, the second locking member 42 is preferably coupled to the elastic restoring member 83. The elastic restoring member 83 stores force when the second locking member 42 is rotated by pulling the link rope 20.
In this embodiment, the first elastic driving member may be a torsion spring or a tension spring; the second elastic driving piece can be a torsion spring or a tension spring. Preferably, the first elastic driving member is a torsion spring, and the second elastic driving member is a tension spring.
As shown in fig. 3 and 4, in a specific implementation of the present embodiment, the reset handle 82 is connected to each of the first spindle lever 31 and the second spindle lever 41. The reset handle 82 may move the first or second spindle rotation rod 31 or 41 connected thereto, so that the first or second spindle rotation rod 31 or 41 connected thereto is restored to the original position. Reset handle 82 may be manually controlled by an operator.
In this embodiment, the number of the second linkages may be one or more, and the number of the second linkages may be selected according to the number of the valve plates in the valve.
When the number of valve plates in the valve is large, the number of the second linkage mechanisms is multiple, one or two second linkage mechanisms are adjacent to the first linkage mechanism, and the rest second linkage mechanisms are sequentially arranged. When one second linkage mechanism is adjacent to the first linkage mechanism, the plurality of second linkage mechanisms are sequentially arranged, and the first linkage mechanism is positioned on one side of all the second linkage mechanisms and is connected with the second linkage mechanism on the side. Specifically, a first main shaft rotating rod in a first linkage mechanism is connected with second locking pieces in adjacent second linkage mechanisms through linkage ropes, and in each second linkage mechanism, the second main shaft rotating rod of one second linkage mechanism is connected with the second locking pieces in the second linkage mechanisms which are adjacent in sequence through the linkage ropes.
When two linkages are adjacent to the first linkage, as shown in fig. 1, for example, the number of the second linkages 40 is three, the number of the first linkages 30 is one, one second linkage 40 is located on the left side of the first linkage 30, and the other two second linkages 40 are located on the right side of the first linkage 30. The first spindle rotation lever in the first linkage 30 is connected with the second locking piece of the second linkage 40 located at the left side thereof and the second locking piece of the second linkage 40 located at the right side thereof, respectively, through the linkage rope 20. The second spindle rotation lever in the second linkage 40 located immediately adjacent to the first linkage 30 and on the right side thereof is connected with the second locking piece in the second linkage 40 located on the rightmost side of the three second linkages 40 through the linkage rope 20.
When the valve linkage device provided in this embodiment is applied to a valve, the valve linkage device may be a single-head linkage (as shown in fig. 5 and 6) or a double-head linkage (as shown in fig. 7). In particular, when the length of the valve plate in the valve is less than 125cm, the valve is more suitable for a single-head linkage mode, namely, a valve linkage device with the structure shown in fig. 5 and 6 is installed. When the length of the valve plate is more than or equal to 125cm, the valve is usually manufactured by dividing the valve into two sections, so that the valve is more suitable for a double-head linkage mode, namely, a valve linkage device with a structure shown in fig. 7 is installed.
Specifically, when the valve linkage device is a single-head linkage, as shown in fig. 5, the first linkage mechanism 30 and each second linkage mechanism 40 are located on the same side of the valve, and each valve plate 90 is driven to rotate on the side of the valve.
When the valve linkage device is in double-head linkage, the valve linkage mechanisms are divided into a first group of linkage mechanisms and a second group of linkage mechanisms, wherein the first group of linkage mechanisms are arranged on one side of the valve, and the second group of linkage mechanisms are arranged on the opposite side of the valve.
As shown in fig. 2, 7 and 8, the first group of linkage mechanisms includes a first linkage mechanism 30 and a plurality of second linkage mechanisms 40, the second group of linkage mechanisms includes a linkage plate 84 and a plurality of second linkage mechanisms 40, a first spindle rotation rod 31 in the first linkage mechanism 30 is connected with the linkage plate 84 through a transmission shaft 85, the first spindle rotation rod 31 can drive the linkage plate 84 to rotate through the transmission shaft 85, and a second locking piece in a second linkage mechanism adjacent to the linkage plate 84 in the second group of linkage mechanisms is connected with the linkage plate 84 through a linkage rope 20. Specifically, the number of the second linkages 40 in the first group of linkages is equal to the number of the second linkages 40 in the second group of linkages, and are disposed on both sides of the corresponding valve plate 90 in a one-to-one correspondence. The first linkage mechanism 30 and the linkage piece 84 are respectively mounted on both sides of the same valve plate 90.
The electric actuating mechanism drives a first main shaft rotating rod in the first linkage mechanism to rotate, the first main shaft rotating rod drives a linkage piece to rotate through a transmission shaft, the first main shaft rotating rod drives each second linkage mechanism in the first group of linkage mechanisms through a linkage rope, and the linkage piece drives each second linkage mechanism in the second group of linkage mechanisms through the linkage rope.
The valve linkage device provided by the embodiment has the following innovation points: the electric actuating mechanism in the valve linkage device is not directly connected with the valve plate, but only plays a role of pulling the first locking piece, so that the first locking piece rotates to be separated from the first main shaft rotating rod, and the first main shaft rotating rod is separated to drive the valve plate to rotate under the elastic action of the first elastic driving piece. The force pulling the first locking piece is far smaller than the force required by directly pulling the valve plate to rotate. In the experimental process, the force required for pulling the first locking piece is only equivalent to the traction force of two electromagnets, and the combination of the traction forces of the two electromagnets is less than 1kg. The rotation of the existing actuating mechanism is generally more than 10N/M (cow's rice). According to the length of the steel rope force arm, the pulling force obtained by conversion can reach 50 kg, which is 50 times of the pulling force required by the valve linkage device provided by the application. The power of the electromagnet used in the device can be saved greatly.
The valve linkage device can save the equipment of a fire-fighting power supply, save engineering investment and improve the reliability of valve action.

In particular, in one embodiment, each set of valves may be coupled to either the first linkage or the second linkage.
Alternatively, as shown in fig. 6, the plurality of valves are divided into a plurality of groups, each group includes a plurality of valves, the valve plates 90 of the plurality of valves in each group are in transmission connection, and the valve plate 90 of one valve in each group is connected with the first linkage mechanism 30 or the second linkage mechanism 40.
With continued reference to fig. 6, the valve assembly preferably further includes a driving plate 91 and a driving rod 92, wherein the driving plate 91 is disposed on the rotation shaft of the valve plate 90 of each valve in the valve assembly, the driving plate 91 is in a cam shape, one end of the driving plate 91 is fixedly connected with the rotation shaft of the valve plate 90, and the other end is hinged with the driving rod 92. One of the valve plates 90 is connected with a valve linkage (a first main shaft rotating rod in the first linkage mechanism 30 or a second main shaft rotating rod in the second linkage mechanism 40) and is driven by the valve linkage to rotate, when the valve plate 90 rotates, a transmission plate 91 connected with a rotating shaft of the valve plate 90 swings, so that other transmission plates 91 in the same group are driven to swing through the transmission rod 92 to drive the valve plates 90 of other valves in the same group to rotate, and synchronous rotation of each valve plate 90 in the valve group is realized.
Finally, it should be noted that: the above embodiments are only for illustrating the technical solution of the present invention, and not for limiting the same; although the invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some or all of the technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit of the invention.
